Summary: Myocardium Infarction (MI) is a leading cause of death worldwide, with pharmacological interventions not being the forefront in improving outcomes. Stem cell-based tissue engineering approaches have shown promise in regenerating the infarcted myocardium. Research using microfluidic devices has provided insights into the pathophysiology of MI, aiding in the differentiation of stem cells and engineering of scaffolds mimicking native cardiac conditions. Delivery of stem cell-loaded engineered scaffolds to the infarction site remains a challenge for future clinical translation.

Summary: Myocardial infarction is a common cardiovascular disease and the leading cause of death worldwide. A 3D printed hydrogel, made from natural polymers, has been developed for cardiac tissue regeneration. The hydrogel, consisting of Gellan gum and Konjac glucomannan, shows excellent printability and possesses proper mechanical properties. It promotes endothelial cells' proliferation and migration, enabling the repair of injured cardiac tissue. This study provides the potential for a simple, low-cost, and efficient cardiac tissue regeneration method using a 3D printed hydrogel for myocardial infarction treatment in the future.

Summary: This study demonstrated that tropoelastin can improve post-MI healing by enhancing cardiac repair and reducing scar formation. Tropoelastin injection significantly improved left ventricular function, reduced scar size, and increased scar elastin content. Furthermore, it promoted elastic fiber formation and reduced immune response. The findings suggest potential therapeutic strategies for manipulating scar synthesis after MI.

Summary: Myocardial infarctions are a common form of cardiac injury and death globally, with the reparative process ultimately leading to scar tissue formation and heart failure. Traditional approaches to studying post-infarct cellular microenvironments have limited control over relevant features, while Organ on a Chip models have emerged as new paradigms for dissecting this complex environment.

Summary: Strategies for stem cell-based cardiac regeneration and repair, specifically cardiac stem cells (CSCs) and the use of cellular spheroids, have shown promising therapeutic potential for ischemic heart disease. The optimized spheroid culture conditions enhance the expression levels of factors related to cardiac regeneration, leading to improved retention rates and significant cardiac regeneration effects in animal models. Intramyocardial administration of CSC spheroids could serve as an advanced therapeutic modality for enhanced cell engraftment and regenerative abilities in cardiac repair post-myocardial infarction.

Summary: Neural crest cells are a versatile stem cell population in vertebrates that can migrate and differentiate into various cell types during embryogenesis. While mammalian hearts lose their regenerative capacity shortly after birth, some vertebrate species, like zebrafish, can self-repair/regenerate after cardiac damage. Recent research has shown the potential of cardiac neural crest cells in cardiac regeneration, using different vertebrate species and pluripotent stem cell-derived neural crest cells. This review summarizes the regenerative capacity of the neural crest in various tissues and organs, focusing on the characteristics and roles of cardiac neural crest cells in cardiac regeneration. The article also discusses potential future applications of neural crest cells in disease treatment.

Summary: Tissue engineering combines engineering and biology to generate living tissue equivalents for drug testing, disease modeling, and regenerative medicine. Progress has been made in developing engineered human cardiac muscle patch (hCMP) and heart tissue analogs, but major obstacles remain, including inadequate scalability, poor integration and engraftment rate, and the lack of functional vasculature. Advanced technologies such as micropatterning and three-dimensional bioprinting have enabled fabrication of hCMP architectures at unprecedented resolution, but challenges still need to be addressed for in vivo tissue repair using hCMP-based strategies.

Summary: This study found significant ROS production in the left heart of mice treated with DOX, but not in the right heart. Transcriptional changes differ between the left and right heart, correlating with myocardial dysfunction. The results emphasize the importance of evaluating parameters of left and right heart function during DOX therapy.

Summary: Protein nanofibrils, specifically lysozyme nanofibrils (LNFs), are used to improve the properties of gelatin electrospun nanocomposite cardiac patches. The addition of LNFs enhances the mechanical properties and antioxidant activity of the patches while maintaining their morphology and biocompatibility. These results demonstrate the potential of LNFs as functional reinforcements for biopolymeric electrospun patches in myocardial infarcted tissue regeneration.

Summary: Blood vessels in adult mammals are highly organized and stable, but in cases of ischemic heart, c-Kit(+) cells play a crucial role in the development and homeostasis of cardiac endothelial cells. Setd4-expressing quiescent c-Kit(+) cells can regulate vascular endothelial cells and improve cardiac function in myocardial infarction injured mice. This suggests the potential for targeted treatments for cardiac ischemic injury by controlling the quiescence of c-Kit(+) cells through epigenetic mechanisms.

Summary: This study found that aged mice have higher baseline inflammation and fewer satellite cells in muscles compared to young mice. After muscle injury, old mice exhibited a muted inflammatory response but increased recruitment of M2 macrophages and IL-10 expression. Reconstitution with young cells partially restored immune responses of old mice to a more youthful state, leading to increased satellite cell proliferation.

Summary: Clinical evidence suggests that the prevalence of cardiac disease is lower in premenopausal women compared to postmenopausal women and men. Uterine stem cells may be a major factor, as a high abundance of these cells are present in the uterus. Our studies show the presence of an utero-cardiac axis, in which uterine stem cells can home to cardiac tissue to promote tissue repair. A triangular relationship among the bone marrow, uterus, and heart is also suggested.

Summary: This study presents a method for constructing a functional cardiac model that mimics the myofiber orientation of the human left ventricle by hierarchically assembling 2D aligned cell sheets. The model is fabricated using microfabricated elastomers and incorporates micro-grooves to guide cell growth and promote cell-cell contact. It also includes rectangular micro-scale holes to improve oxygen diffusion within the model. The model showed high cell viability and provided functional readouts such as calcium transients and ejection fraction.

Summary: Conductive polymers have been investigated as a potential solution for rewiring cardiac tissue to restore proper electrical signaling. In this study, a specific conductive polymer (PAMB-G) was fabricated and implanted onto the atrium of a rat model with atrial fibrillation (AF). The results showed that the PAMB-G group had improved AF recovery and higher conduction velocity compared to the control group, indicating the suitability of PAMB-G as a medium for restoring proper cardiac electrical signaling in AF hearts.

Summary: Myocardial fibrosis, resulting from myocardial infarction, alters cardiac electrophysiological properties and can lead to arrhythmias. A new bio-conductive epicardial patch has been developed and shown to synchronize cardiomyocytes and alleviate atrial fibrillation in rat hearts. This patch could potentially be a novel approach for the treatment of cardiac arrhythmias.
